Staff

The treatment team at The Ranch Tennessee includes clinicians, nurses, recovery counselors, equine specialists, and support staff who guide clients through daily work on the land. Their approach reflects The Ranch Philosophy—steady, practical, and rooted in responsibility and compassion.

Addiction specialists and holistic treatment experts

Our addiction specialists in Tennessee and holistic treatment experts support clients through clinical sessions and outdoor experiences. Together, they help people build emotional awareness and resilience. 

Examples of their work include: 

  • Leading individual and group therapy 
  • Guiding equine-assisted sessions 
  • Supporting outdoor and movement-based practices 
  • Maintaining safe, structured daily routines  

How our team works with land and animals

The land is a partner in the healing process. Our equine therapists in Tennessee help clients strengthen trust, confidence, and emotional regulation through hands-on work with horses. Staff support reflective outdoor time and use The Ranch environment to encourage grounded, practical growth.

Brian Fuller, MD

Medical Director

Dr. Fuller is board certified by the American Board of Psychiatry and Neurology. He completed medical school at the University of Tennessee Health Science Center and residency at Vanderbilt University. Additionally, he has completed the Nashville Advance Psychodynamic Psychotherapy Program, a two-year intensive program to better integrate traditional psychotherapy into his psychiatric practice. Dr. Fuller began his post-residency career in psychiatry running a psychotherapy-oriented private practice. Looking to help more people than he could working alone yet still provide treatment that emphasizes the importance and value of talk therapy, he joined The Ranch in 2017.

Dr. Fuller is passionate about helping people who have survived trauma and/or are struggling with addiction and strongly believes that the life we all deserve is within reach, no matter the adversity that one must overcome. He views medications as tools rather than solutions and his prescribing philosophy is to use the lowest dose necessary of non-addictive medications to help aid the process of recovery.
